The Thai 6-hour clock (ตี, โมงเช้า, บ่าย, เย็น, ทุ่ม)

The Thai 6-Hour Clock

When telling time, Thai speakers typically use a traditional six-hour clock system. Instead of counting up to 12 or 24, the day is divided into distinct periods, each with its own time marker.

To say "at" or "during" a certain time, use the word ตอน before the time phrase.

Early Morning and Morning

For the early hours of the morning (1:00 AM to 5:00 AM), use ตี followed by the number.

For the daytime morning hours (7:00 AM to 11:00 AM), use the number followed by โมงเช้า. In this system, you count from 1 to 5 starting at 7:00 AM. For example, 8:00 AM is the second hour of the morning.

Afternoon and Late Afternoon

In the early afternoon (1:00 PM to 3:00 PM), place บ่าย before the number, and add โมง at the end.

For the late afternoon (4:00 PM to 6:00 PM), use the number followed by โมง and then เย็น.

Evening and Night

For the evening and night (7:00 PM to 11:00 PM), use the number followed by ทุ่ม. Similar to the morning, you count from 1 to 5 starting from 7:00 PM. This means 7:00 PM is the first hour of the evening.

To say "half past" any hour, simply add ครึ่ง at the very end of the time phrase.
